ELASTIC FLEXIBLE PIPE DEVICE |
摘要 |
<p>An expandible plug-like device is disclosed for insertion into a conduit for closing or sealing off the conduit. The device has a flexible and elastic hose that is reinforced by at least two reinforcement plies made of flexible metal cables. The hose is secured at least one end of the device by the reinforcement plies being locked or held by rigid closure elements. These elements include an inner support element, an outer support element and a bottom seal sealing element. The inner and outer elements have conical locking surfaces which diverge towards one end of the device and a wedge is arranged between the end edges of the reinforcement plies in order to lock the plies against the support element and the reinforcement element.</p> |
